Overview
The STP08DP05XTTR is a monolithic, low voltage, low current power 8-bit shift register designed specifically for LED panel displays. This component, produced by STMicroelectronics, integrates a 8-bit serial-in, parallel-out shift register that feeds a 8-bit D-type storage register. The output stage features eight regulated current sources capable of providing 5-100 mA constant current to drive LEDs. It is backward compatible with the STP8C/L596 and enhances functionality with the addition of open and short detection on the outputs.
